ANTICORROSION COATING COMPOSITION Russian patent published in 2010 - IPC C09D167/08 C09D5/08 

FIELD: chemistry.

SUBSTANCE: invention relates to protection and restoration of corroded metal surfaces working under abrasive wearing conditions, used in atmospheric conditions of different climatic zones, in the atmosphere of aggressive media, for example in power engineering, chemical and mining industry when repairing rusty equipment. The anticorrosion coating composition contains the following components in wt %: 21-35% modified alkyd filming agent, 1-2% rheological additive - surfactant based on TROYSOL fatty amine, 0.5-1% siccative, 4-12% filler, 5-10% zinc phosphate, 1-3% rust solvent based on tannins and tannin derivatives, specularite with high content of Fe₂O₃ and consisting of different fractions, 20-30% specularite of the first fraction with particle size not less than 63 mcm, 6-15% specularite of the second fraction with particle size not greater than 20 mcm, organic solvent - the rest.

EFFECT: proposed composition has good anticorrosion properties, abrasive wear resistance, high durability, is capable of dissolving rust without thorough preparation of the metal surface.
